It's not just women who are made uncomfortable, either. Child attendees and any accompanying adults may find this unwelcome (or frightening, depending on the content) too, and men often also for various reasons do not want to view sexual material. Anyone attending the event in a work context — geek technical conferences often have attendees who are only geeks on work time — will be unprepared for material that wouldn't be welcome when described in their work environment.

However, such presentations should be made to a consenting audience. This means:

make the expectation of sexual or confronting material clear to attendees in advance (this may be clear from the nature of the event, but if in doubt, explicit statements are better).

make it clear that audience members may freely leave a talk or activity at any time and for any reason, and that they will not be called upon to explain or justify themselves.

place emphasis on being inclusive of different sexual orientations and preferences.

take extra care to emphasize what content or behaviour is not welcome (examples might include repeated sexual approaches, other harassment, hate speech)

if the entire event is sexual in nature, have a designated "chill out" space for people who don't want to participate in sexual activities or discussions at any given moment.

In these environments, speakers will still wish to consider issues of Body image and Othering in choosing their content and imagery: for example, does it assume that the audience is all male and heterosexual? Does it show a range of body types, or only stereotypically attractive slender young able-bodied white folk?
